Jeff,

Personally, I wouldn't use any muffler that has parts inside it that could
(will) break off and possibly plug the exit.  This is what happened to the
Mistral rotary which resulted in an off-field landing into trees.

The attach method should be two overlapping tabs with matching holes for th=
e
bolt.  That way the bolt won't be subjected to the exhaust heat.

Mark S.
Now on muffler #5
